Macrogol 4000 Casen Recordati (Macrogol 4000)

Macrogol 4000 is used as an osmotic laxative to manage conditions affecting bowel motility and to facilitate diagnostic procedures.

• Constipation: softens stool and promotes bowel movements in occasional and chronic constipation.
• Bowel preparation for colonoscopy: clears the intestinal tract to improve visualization during endoscopic examinations.
• Opioid‑induced constipation: counteracts reduced gastrointestinal motility caused by opioid therapy.
• Chronic idiopathic constipation: provides long‑term relief for patients with persistent functional constipation.

• Macrogol 4000 is a high‑molecular‑weight polyethylene glycol that is poorly absorbed from the gastrointestinal tract. It retains water within the intestinal lumen by creating an osmotic gradient, increasing stool volume and softness, which stimulates peristalsis and facilitates the passage of feces without significant electrolyte shifts.

Macrogol 4000 may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Abdominal bloating: sensation of fullness or swelling in the abdomen.
• Flatulence: increased intestinal gas production.
• Nausea: mild feeling of queasiness.
• Diarrhea: loose or watery stools.
• Abdominal cramps: intermittent pain or discomfort.
• Headache: mild to moderate head pain.

Serious or Rare Side Effects

• Severe electrolyte imbalance: abnormal levels of sodium, potassium, or other electrolytes.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Severe abdominal pain: intense or persistent pain requiring medical attention.
• Dehydration: excessive fluid loss leading to dizziness or low blood pressure.

When prescribing or dispensing Macrogol 4000, consider the following safety measures.

• Assess hydration status: ensure the patient is adequately hydrated before use.
• Renal impairment: use with caution in patients with reduced kidney function.
• Intestinal obstruction: avoid in cases of mechanical blockage of the bowel.
• Electrolyte monitoring: watch for signs of electrolyte disturbances during prolonged therapy.
• Pediatric use: administer under medical supervision in children.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Macrogol 4000 can interact with other medications that affect gastrointestinal function or fluid balance.

Major Interactions (Avoid)

• Concurrent osmotic laxatives: may cause excessive fluid loss and electrolyte imbalance.
• Diuretics: increased risk of dehydration and electrolyte disturbances.
• Anticholinergic agents: may reduce the laxative efficacy of macrogol.

Moderate Interactions (Monitor Closely)

• NSAIDs: may increase gastrointestinal irritation when combined.
• Opioid analgesics: may counteract the laxative effect, requiring dose adjustment.
• Certain antacids: may alter the osmotic activity of macrogol, affecting stool consistency.
